Feature-driven anomaly flagging in obscured active galactic nucleus light curves with autoencoders

Natale De Bonis, Demetra De Cicco, Stefano Cavuoti +5

Active galactic nuclei (AGN) are among the most complex classes of astrophysical objects, displaying a wide range of variability and observational properties. Identifying unusual A…

VAR-PZ: Constraining the Photometric Redshifts of Quasars using Variability

S. Satheesh-Sheeba, R. J. Assef, T. Anguita +33

The Vera C. Rubin Observatory LSST is expected to discover tens of millions of new Active Galactic Nuclei (AGNs). The survey's exceptional cadence and sensitivity will enable UV/op…
